Hello,
In first assignment, my code is working fine and giving correct result. But i am unable to validate it.
Validate is giving below error:
jsonschema.exceptions.ValidationError: Notebook failed to validate; the nbgrader metadata may be corrupted.
On submission also, i am getting same error.
Can you please help me in resolving this?
Most likely that means that your notebook is damaged in some way. Some of the “metadata” that is in the notebook that you can’t directly see has been modified. The best idea is to follow this thread to get a fresh copy of your notebook. Then very carefully “copy/paste” over just your completed code from the “YOUR CODE HERE” sections into the clean copy.
Please give that a try and let us know if that does not help.
